Description

Technical Field

[0001] The present invention relates to the field of pipe corridors, and in particular to a prefabricated waterproof underground pipe corridor. Background Art

[0002] Prefabricated waterproof underground pipe gallery is a modern urban infrastructure that can integrate multiple pipelines such as power, communication, water supply, and drainage. It uses prefabricated component technology to complete the main pipe gallery production in the factory and then transport it to the site for assembly to form an underground passage pipe gallery system with waterproof function.

[0003] The Chinese patent with the publication number of "CN113737856A" discloses "an underground pipe gallery, comprising an outer wall (1), wherein the outer wall (1) contains an upper transverse partition (2) and a lower transverse partition (3) spaced apart from each other, and a smoke exhaust ventilation channel (4) is formed between the upper part of the outer wall (1) and the upper transverse partition (2). Although it can play the role of "the underground pipe gallery not only ensures the functions of urban transportation and municipal pipe gallery, but also reduces energy waste, and achieves the purpose of intensive design, green environmental protection, and three-dimensional underground space", when the underground pipe gallery is in use, the pipe gallery As a fixed structure, the angle of the pipe gallery cannot be adjusted after it is installed underground. It is necessary to adjust the parallel angle by hoisting during laying and then connect multiple pipe galleries. This makes it difficult to adjust the angle during laying and connecting. In addition, the fixed structure of the pipe gallery is easily damaged when impacted and cannot maintain a stable state. At the same time, when water leakage occurs in the pipe gallery, the water cannot be discharged in time, which will cause water accumulation in the pipe gallery and make it impossible to use safely. After the pipe gallery is buried underground, the pipe gallery is also susceptible to long-term moisture intrusion, which causes the moisture in the pipe gallery to accelerate the rust of metal components, thereby reducing the service life of the pipe gallery. Summary of the Invention

[0004] The main purpose of the present invention is to provide a prefabricated waterproof underground pipe gallery, which can effectively solve the technical problems raised by the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0007] As a further solution of the present invention, a bin cover is fixedly installed on the upper end of the sewage pipe bin and the thermal bin, and a spare cable bin is opened inside the pipe gallery body below the thermal bin.

[0008] As a further solution of the present invention, the extended mounting plate passes downward through the rotating slot, and the shielding plate is located below the rotating slot and is closely connected to the inner wall of the pipe gallery body.

[0009] As a further solution of the present invention, the buffer structure includes a damping shock absorber, a shock absorbing spring and a tensile connecting frame. The damping shock absorber is fixedly installed at both ends of the rotating slot, the shock absorbing spring is sleeved on the outside of the damping shock absorber, and the tensile connecting frame is sleeved on the outside of the shock absorbing spring and fixedly connected to the end of the damping shock absorber.

[0010] As a further solution of the present invention, the damping shock absorber is inserted into the inner wall of the tunnel body, and the upper end of the retractable steel rope is passed upward around the guide wheel and passes through the extension mounting plate and is fixedly connected to the stretching connecting frame.

[0011] As a further solution of the present invention, a one-way valve is fixedly installed inside the water guide hole, and the water guide hole penetrates downward to the outside of the pipe gallery body.

[0012] As a further solution of the present invention, the connecting pipe structure includes a steel pipe slot, a connecting steel pipe and a steel pipe through-hole. The steel pipe slot is integrally formed on the inner wall of the pipe gallery shell, the connecting steel pipe is movably installed on the inner side of the steel pipe slot, and multiple steel pipe through-holes are opened on the pipe wall of the connecting steel pipe.

[0013] As a further solution of the present invention, the outer wall of the tunnel body is fitted with the connecting steel pipe, the steel pipe through-hole passes through the pipe wall of the connecting steel pipe, a drainage pipe is provided at the rear bottom of the tail end plate, a drainage port is welded at the rear end of the drainage pipe, and the front end of the drainage pipe is fixedly connected to the rear end of the connecting steel pipe below.

[0016] Compared with the existing technology, the present invention has the following beneficial effects: when the main body of the pipe gallery is constructed, the main body of the pipe gallery is pulled to rotate, so that the main body of the pipe gallery rotates on the connecting steel pipes, while the outer shell of the pipe gallery remains stationary, thereby changing the parallel angle of the main body of the pipe gallery after the pipe gallery is laid, eliminating the trouble of angle adjustment during laying and docking, and making it more convenient to adjust the docking angle during the construction of the pipe gallery;

[0017] When the main body of the pipe gallery is impacted, the impact will be transmitted to the main body of the pipe gallery. The main body of the pipe gallery is located inside the outer shell of the pipe gallery and rotates and swings on the connecting steel pipe. Then the retractable steel rope and the stretching connection frame are pulled to move. Then the contraction of the shock-absorbing spring and the damping shock absorber is used to achieve the swing buffering of the main body of the pipe gallery, so that the main body of the pipe gallery remains stable, preventing the pipe gallery from being damaged by impact and collision, and ensuring longer and more stable use.

[0018] When water leaks in the sewage pipe warehouse and thermal warehouse, the water is discharged into the space between the main body and the outer shell of the pipe gallery, and then the leaked water is discharged along the connecting steel pipe to the end and discharged from the drain port on the drain pipe, thereby diverting and discharging the leaked water, preventing water accumulation in the pipe gallery when leaking, and making it safer to use;

[0019] When the air humidity that the main body of the tunnel is exposed to is too high, dry air is sent into the space between the tunnel shell and the main body through the connecting steel to achieve ventilation between the tunnel shell and the main body, maintain the dryness requirement of the main body of the tunnel, prevent the moisture in the tunnel from accelerating the rust of metal components, and improve the service life of the tunnel.

The sewage pipe bin 2 and two thermal bins 3 are opened at the lower part of the interior of the pipe gallery body 1, and the sewage pipe bin 2 is located in the middle of the two thermal bins 3. The electric bin plate 6 is integrally formed above the inner wall of the pipe gallery body 1. The tail end plate 23 is located at the rear end of the pipe gallery body 1. A rotating slot 7 is provided at the middle top of the pipe gallery body 1. Buffer structures 8 are fixedly installed at both ends of the rotating slot 7. The outside of the pipe gallery body 1 is covered with a pipe gallery shell 12 fixedly connected to the inner wall of the tail end plate 23. Connecting pipes are provided on both sides and below the inner wall of the pipe gallery shell 12. Structure 13, two extended mounting plates 17 are integrally formed just above the inner wall of the pipe gallery shell 12, and a baffle plate 21 is welded to the lower end of the extended mounting plate 17. A retracting wheel 18 is fixedly installed on one side of the lower end of the baffle plate 21, and a retracting knob 19 is fixedly installed on the front end of the retracting wheel 18. A retracting steel rope 20 is wrapped around the outside of the retracting wheel 18, and a guide wheel 22 is fixedly installed on one side of the extended mounting plate 17. A gas transmission structure 26 is provided behind the tail end plate 23. A plurality of drainage holes 30 are provided on the upper inner walls of the sewage pipe bin 2 and the thermal bin 3. A water guide hole 31 that passes through the drainage hole 30 is provided inside the pipe gallery body 1 between the sewage pipe bin 2 and the thermal bin 3.

[0031] In this embodiment, a bin cover 4 is fixedly installed on the upper end of the sewage pipe bin 2 and the thermal bin 3, and a spare cable bin 5 is opened inside the corridor body 1 below the thermal bin 3. The bin cover 4 serves to seal the sewage pipe bin 2 and the thermal bin 3, and the spare cable bin 5 is used to increase the laying of cable lines.

[0032] In this embodiment, the extended mounting plate 17 passes downward through the rotating slot 7, and the baffle plate 21 is located below the rotating slot 7 and is closely connected to the inner wall of the tunnel body 1. The baffle plate 21 serves to cover the rotating slot 7, and when the tunnel body 1 and the rotating slot 7 rotate, the fixed baffle plate 21 can keep covering the rotating slot 7.

[0033] In this embodiment, the buffer structure 8 includes a damping shock absorber 9, a shock-absorbing spring 10 and a tensile connecting frame 11.

The contraction of the shock-absorbing spring 10 and the damping shock absorber 9 achieves a shock-absorbing and buffering effect.

[0034] In this embodiment, the damping shock absorber 9 is inserted into the inner wall of the tunnel body 1, and the upper end of the retractable steel rope 20 is passed upward around the guide wheel 22 and passes through the extension mounting plate 17 and is fixedly connected to the stretching connecting frame 11. The retractable steel rope 20 pulls the shock absorbing spring 10 and the damping shock absorber 9 to retract through the stretching connecting frame 11.

[0035] In this embodiment, a one-way valve 32 is fixedly installed inside the water guide hole 31, and the water guide hole 31 penetrates downward to the outside of the pipe gallery body 1. The one-way valve 32 allows the water guide hole 31 to only drain water downward, and water cannot flow upward from the one-way valve 32 into the water guide hole 31.

[0036] In this embodiment, the connecting pipe structure 13 includes a steel pipe slot 14, a connecting steel pipe 15 and a steel pipe through-hole 16. The steel pipe slot 14 is integrally formed on the inner wall of the pipe gallery shell 12, and the connecting steel pipe 15 is movably installed on the inner side of the steel pipe slot 14. Multiple steel pipe through-holes 16 are opened on the pipe wall of the connecting steel pipe 15, and the steel pipe through-holes 16 have the effect of guiding water and air.

[0037] In this embodiment, the outer wall of the tunnel body 1 is fitted with the connecting steel pipe 15, and the connecting steel pipe 15 rotates to cooperate with the rotation of the tunnel body 1. The steel pipe through hole 16 penetrates the pipe wall of the connecting steel pipe 15. A drain pipe 24 is provided at the rear bottom of the tail end plate 23, and a drain port 25 is welded to the rear end of the drain pipe 24. The front end of the drain pipe 24 is fixedly connected to the rear end of the connecting steel pipe 15 below. The water in the connecting steel pipe 15 flows into the drain pipe 24 and is then discharged from the drain port 25.

[0038] In this embodiment, the gas transmission structure 26 includes an annular pipe 27, an air supply pipe 28 and a blower 29. The annular pipe 27 is located at the rear top of the tail end plate 23, the air supply pipe 28 is fixedly installed at the lower end of the annular pipe 27, and the blower 29 is fixedly installed at the front end of the air supply pipe 28.

[0039] In this embodiment, the annular pipe 27 is fixedly connected to the rear ends of the connecting steel pipes 15 on both sides. The annular pipe 27 is located above the drain pipe 24, and the blower 29 inputs air into the connecting steel pipe 15 through the air supply pipe 28 and the annular pipe 27.

[0040] It should be noted that the present invention is a prefabricated waterproof underground pipe gallery. When in use, the pipe gallery main body 1 and the pipe gallery shell 12 are prefabricated and then buried underground. A plurality of pipe gallery main bodies 1 and pipe gallery shells 12 are docked to form an underground pipe gallery passage. The sewage pipe warehouse 2 is used to lay sewage pipes, the thermal warehouse 3 is used to lay thermal transmission pipes, and the power warehouse plate 6 is used to erect power lines. At the same time, the pipe gallery main body 1 is provided for operators to walk, so that the pipes and lines are laid underground and have a sealing and waterproof effect.

[0041] When the tunnel main body 1 is being built, the retracting wheel 18 is driven to rotate by the retracting knob 19, so that the retracting wheel 18 retracts and releases the retracting steel rope 20. Then the retracting steel rope 20 pulls one end of the rotating slot 7 through the buffer structure 8, thereby pulling the tunnel main body 1 to rotate, so that the tunnel main body 1 rotates on the connecting steel pipe 15, while the tunnel shell 12 remains stationary. Then, the retracting wheel 18 is positioned to change the parallel angle of the tunnel main body 1.

[0042] When the pipe gallery main body 1 is in use for a long time, the impact received will be transmitted to the pipe gallery main body 1, and the pipe gallery main body 1 is located in the pipe gallery shell 12 and rotates and swings on the connecting steel pipe 15, while making the retractable steel ropes 20 on both sides of the top pull the stretching connecting frame 11, and then the stretching connecting frame 11 pulls the shock-absorbing spring 10 and the damping shock absorber 9 to contract, so as to utilize the contraction of the shock-absorbing spring 10 and the damping shock absorber 9 to achieve the swing buffering of the pipe gallery main body 1, so that the pipe gallery main body 1 remains in a stable state;

[0043] When water leaks in the sewage pipe bin 2 and the thermal bin 3, the water level overflows the drain hole 30 and flows in from the inside thereof, flows into the water guide hole 31, and then moves downward to be discharged between the pipe gallery body 1 and the pipe gallery shell 12. Then, the water contacts the connecting steel pipe 15 and penetrates into it from the steel pipe through hole 16 on the connecting steel pipe 15. Therefore, the leaked water flows along the connecting steel pipe 15 to the end and is discharged from the drain port 25 on the drain pipe 24, thereby realizing the diversion and discharge of the leaked water;

[0044] When the humidity of the air that the tunnel main body 1 comes into contact with is too high, the blower 29 transports dry air to the air supply duct 28 and the annular duct 27, so that the air enters the multiple connecting steel pipes 15 on both sides, and then the air is discharged along the steel pipe through holes 16 on the connecting steel pipes 15 and enters between the tunnel shell 12 and the tunnel main body 1, thereby realizing ventilation between the tunnel shell 12 and the tunnel main body 1 and maintaining the dryness requirement of the tunnel main body 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
